    摘要： Object of the present invention is a system for detecting the spatial position and tracking the movement of one or more objects provided with RFID Tags, said objects possibly being positionable on a suitable limited surface, which constitutes the test space. Such objective is achieved realizing a suitable sensorized test surface, on which elements provided with RFID identifier and magnetic marker can be positioned, possibly moved and monitored. Said surface houses a single RFID antenna dimensioned and positioned in such a way as to cover the entire area of interest, and able to read the tags of possible objects, coupled with a series of magnetic sensors, which are positioned in such a way as to ensure the coverage of the test area and whose measuring ranges may also be different according to the peculiarities of the areas of interest (overall area, precision of detection required, presence of particular areas of interest, etc.) and are partially overlapped. The localizable objects or elements are also provided, in addition to a unique identifier, or RFID Tag, with a suitable magnetic marker, adapted to interact with the above-mentioned grid of sensors. The analysis of the tagged objects, thus, occurs in two steps: the identification of the elements is carried out by means of RFID techniques and, particularly, through the interaction between the Tag and the antenna, while the position and movement detection of the tagged elements is carried out by the proximity detection (with interpolation techniques) of the magnet placed on the traceable object and by means of magnetic sensors positioned on the surface.
